Arteries and Veins
Say: ar-tuh-reez and vayns
If you've ever seen a road map, you probably saw many roads going here, there,
and everywhere. Your body has a highway system all its own that sends blood to and
from your body parts. It's called the circulatory system and the roads are called
arteries and veins. Arteries, which usually look red, carry blood away from the heart. Veins, which usually look blue,
return blood to the heart.
